Question

<?php
$s1="";$s2="qwe";$s3="zxc";

if(!empty($s1))
{
    $result=$s1;
}
else
{
    if(!empty($s2))
    {
        $result=$s2;
    }
    else
    {
        $result=$s3;
    }
}

echo "$result";
?>

Is there any possible code, probably of 1-2 lines, replacing the above mentioned code, I remember something like using “or” operator to do what I am doing with this code.

Answer 1

$result = $s1 ? $s1 : ($s2 ? $s2 : $s3);

Or even shorter, if you have PHP >5.3:

$result = $s1 ?: ($s2 ?: $s3);
